Following Andrew's comment, I'd add this paragraph here: -----------8<------------------------ We are not using the existing mempool kernel API since this requires the slab allocator to be available (for pool->elements allocation). A subsequent kmemleak patch will replace the static early log buffer with the pool allocation introduced here and this functionality is required to be available before the slab was initialised. -----------8<------------------------ (patch updated locally) -- Catalin
